The factors of 16 are 1, 2, 4, 8, and 16. The factors of 21 are 1, 3, 7, and 21. The only common factor is 1; they are relatively prime. The least (or lowest) common factor is 1. The greatest (or highest) common factor is 1.
The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.The common factors of 24 and 36 are 1, 2, 3, 4, 6, and 12. Therefore, the least (smallest) common factor is 1.The lowest common factor of any set of positive integers is 1.The least common factor of any set of integers is 1.

The lowest term of 3/9 is 1/3. Basically find the least common factor (LCF) of 3 and 9 and divide both the numerator and the denominator by LCF. Another example is 2/4. LCF = 2 (2/2)/(4/2) = 1/2 1/2 is the lowest term of 2/4.
The LCD for 3/4 and 4/7 is 28.
The lowest common denominator is simply the lowest real number that two separate denominators can be converted to. Fractions are easier to add, subtract, and compare when they are in terms of the same denominator.For example, we will use the numbers 1/3 and 1/4. First find the lowest common multiples (LCM).3:3,6,9,124:4,8,12Now that you have found the lowest common multiple, you find an equivalent fraction that has the same value.1/3 * 4/4 = 4/121/4 * 3/3 = 3/12When you multiply the denominator by a number, you have to do the same for the numerator. This is called the Property of One. Now you add the two fractions together.4/12 + 3/12 = 7/12
In math terminology, "least" means smallest or lowest. The least common factor is the smallest factor that is common to all the numbers being compared. Look at the results in the following examples.Examples:What is the least common factor of 19 and 24?The factors of 19 are 1 and 19.The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.The only common factor is 1, so the least common factor is 1.What is the least common factor of 30 and 36?The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.The common factors are 1, 2, 3, and 6, so the least common factor is 1.What is the least common factor of 28 and 42?The factors of 28 are 1, 2, 4, 7, 14, and 28.The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The common factors are 1, 2, 7, and 14, so the least common factor is 1.What is the least common factor of 96 and 120?The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96.The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.The common factors are 1, 2, 3, 4, 6, 8, 12, and 24, so the least common factor is 1. As you can see, the smallest factor of two or more numbers is 1.
To find the greatest common factor (GCF) of 12, 60, and 68, we first need to find the prime factorization of each number. The prime factorization of 12 is 2^2 * 3, the prime factorization of 60 is 2^2 * 3 * 5, and the prime factorization of 68 is 2^2 * 17. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 2^2 = 4. Therefore, the greatest common factor of 12, 60, and 68 is 4.
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1.
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 12, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 12 are 1, 2, 3, 4, 6, and 12. Examples: The common factors of 7 and 12 are only 1; the greatest common factor is 1. The common factors of 12 and 16 are 1, 2, and 4; the greatest common factor is 4. The common factors of 12 and 18 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 12 and 30 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 12 and 34 are 1 and 2; the greatest common factor is 2. The common factors of 12 and 44 are 1, 2, and 4; the greatest common factor is 4. The common factors of 12 and 96 are 1, 2, 3, 4, 6, and 12; the greatest common factor is 12.
The factors of 32 are 1, 2, 4, 8, 16, and 32. The factors of 108 are 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, and 108. The common factors are 1, 2, and 4. The largest factor they have in common is 4, so the greatest common factor is 4. You can also determine the greatest common factor by their prime factors. The prime factors of 32 are 2, 2, 2, 2, and 2. The prime factors of 108 are 2, 2, 3, 3, and 3. The prime factors they have in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.
